Route notes
Why this routing works
This multi-stop routing sequences two shorter European-area stays before the longest stop in Melbourne, then closes the loop back to New York City. With 4 nights in Reykjavik, 3 nights in Thira, and 9 nights in Melbourne, the structure keeps the earlier stops brief and places the most time at the farthest point of the itinerary.
For ticketing, this works as an open-jaw style multi-stop fare rather than separate round-trips, which helps keep the route connected under one plan. The order is straightforward: New York City to Reykjavik, onward to Thira, then a long-haul segment to Melbourne, followed by the return to New York City.
Timing matters on a route like this because the longest flighting comes late in the itinerary. A June departure places the trip in the apr-jun season window, and the 2-week overall duration means each stop is clearly defined rather than left flexible. In economy, this is best approached as a paced but efficient long-distance routing with limited stop count and clear progression between regions.
